41a9f72f78 gpu: host1x: Add API for reading actmon count 
Add API for reading the activity monitor average count for VIC,
NVENC, and NVDEC. There is currently no support for initializing
actmon, so this relies on someone else on a virtualized system
having initialized it (and mapped the actmon region read-only).
